SAMUEL LIPSON, OF SAUGUS, MASSACHUSETTS, ASSIGNOR OF ONE-THIRD TO HARRYROSENBURG AND ONE-THIRD TO JACOB ROSENBURG, OF BOSTON, MASSACHUSETTS.

GARMENT-CEMENTING MACHINE.

To all whom it may concern:

Be it known that I, SAMUEL LIPSON, a citizen of the United States,residing at Saugus, in the county of Essex and State of Massachusetts,have invented an Improvement in Garment-Gementing Machines, of which thefollowing is a specification.

This invention relates to certain improvements in the machine disclosedin my prior Patent #642,344, and more particularly to certainimprovements in the means for delivering and applying the cement to thework by means of a fountain brush, which is especially adapted for usein applying thereto readily flowing cement. In the device of said priorpatent, a cement applying means, of the above described character wasemployed, but said device did not operate satisfactorily for the reasonthat the drag of the brush, on the material which was being cemented,was not uniform and was so great that it was diflicult, or practicallyimpossible to feed the material as rapidly as was desired, or withoutcausing it to become wrinkled and pulled out of position, so thatuniform application of the cement to the surface, at the points desired,was prevented.

The object of the present invention is to provide a cementing meansapplicable to the brush-applying means above referred to, which willenable the work to be fed evenly and smoothly beneath the brush, andwhich will cause the brush frictionally to engage the work withpractically the same force under all conditions, and will also cause thework to be fed rapidly and smoothly beneath the brush. I accomplish thisobject by the means shown in the accompanying drawing, in which,

Figure l is an elevation of the head of a machine, such as is shown inmy said prior patent. Fig. 2 is an elevation of the cement-applyingdevice provided with my improvements. Fig. 3 is an enlarged sectionalview thereof. Fig. 4 is a sectional view on the line 4-4, of Fig. 3.Fig. 5 is a similar view on the line 5-5 of Fig. 3.

In the drawing a indicates the table of the machine and b the headthereof, on which the cement-feeding devices are arranged c indicatingthe cement tank and (Z the tube into which the cement is fed, said tubebeing adapted to reciprocate vertically and a spring 8 being providedfor pressing said tube downward.

form of a link chain, is arranged to be fed over the feed-rollers f, andover a supporting portion a of the table, slightly above the level ofthe surface of the table, and presser rolls 9 are arranged to bear onthe table adjacent the middle thereof in front of and in rear of saidtube (Z, to provide a frictional engagement between the table and thework. A fountain brush it is connected to the lower end of the tube (Z,directly between said rolls 9, said brush having a hollow base,providing a chamber h therein from which a tube 7L leads, so as todeliver the cement into the brush adjacent the base of the bristlesthereof, the brush operating in the manner common to brushes of thistype.

I have found, in practice, that the feeding means already described isinsuflicient to provide a proper feeding of the work beneath the brush,as the drag of the bristles is so great that the material, which isoftentimes thin and easily pulled out of shape, is wrinkled so that thecement is not evenly applied.

According to my invention I provide a two-part ring 2' which is adaptedto be clamped about the brush near the face of the bristles thereof toact as bridle therefor, said ring being rigidly connected to the base ofthe brush by means of one or more arms A pair of rolls in are mounted inforks on the lower ends of a corresponding pair of rods m, said rodsbeing mounted to reciprocate vertically in the ring 2', and having stopcollars n at their upper ends to limit the downward movements thereof.Springs 0 are provided between a shoulder on the lower end of each rodand the under side of the ring 2', for pressing said rollers downwardly,said stops 1?. being arranged so that said rollers 72 may be pressed bytheir respective springs a short distance below the level of the lowerend of the brush. With this arrangement, when the work is fed beneaththe brush, said rolls 9 and is will bear on the work in front and in therear of, and closely adjacent the side edges of the brush, thus pressingit firmly on the feeding table 6, at all sides of the brush, so that thework will be frictionally engaged by and fed by the table, as the tablemoves, and the frictional engagement of the brush on the work will beovercome. The work will also be held flat and smooth, so that the cementwill be evenly applied. The rolls 7a with their supporting means, alsoact to support the brush in a constant relation to the surface of theWork, so that the brush is always pressed thereagainst withapproximately the same force and the drag of the brush on the work isuniform. The manner in which the brush operates, in applying the cement,also does not appreciably vary under normal conditions.

I claim In a cementing-machine, a vertically movable, downwardlyactuated cementing brush, a depending arm mounted on the base thereof, abridle ring extending about the brush and supported on the end of saidarm, a 15 pair of rods mounted to reciprocate vertically in said ring atopposite sides thereof and having supporting rollers in their lowerends, and springs on said rods for holding said rolls adjacent the faceof the brush, substantially as described.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing Witnesses.

SAMUEL LIPSON.
